E-Testing based on service oriented architecture

The extensive use of technology in learning and working, is forcing its use in the assessment process. A lot of software packages exist in the market to realize automated assessment. Several of them are very comprehensive, but most of them are stand alone applications without possibilities for interoperability, adaptability according to learner characteristics and possibilities for content reuse. In this paper we describe the purposes and the process of designing an interoperable E-Testing Framework by remodelling an existing E-Testing system and introducing new structured Service Oriented Architecture, based on encapsulating existing business functions as loosely coupled, reusable, platform-independent services which collectively realize required business objectives. This common framework should support interoperable content, exchange of data and learner profiles, and give the possibility for search and retrieval of any data bank content in local and remote repositories

ERP implementation methodologies and frameworks: a literature review

Enterprise Resource Planning (ERP) implementation is a complex and vibrant process, one that involves a combination of technological and organizational interactions. Often an ERP implementation project is the single largest IT project that an organization has ever launched and requires a mutual fit of system and organization. Also the concept of an ERP implementation supporting business processes across many different departments is not a generic, rigid and uniform concept and depends on variety of factors. As a result, the issues addressing the ERP implementation process have been one of the major concerns in industry. Therefore ERP implementation receives attention from practitioners and scholars and both, business as well as academic literature is abundant and not always very conclusive or coherent. However, research on ERP systems so far has been mainly focused on diffusion, use and impact issues. Less attention has been given to the methods used during the configuration and the implementation of ERP systems, even though they are commonly used in practice, they still remain largely unexplored and undocumented in Information Systems research. So, the academic relevance of this research is the contribution to the existing body of scientific knowledge. An annotated brief literature review is done in order to evaluate the current state of the existing academic literature. The purpose is to present a systematic overview of relevant ERP implementation methodologies and frameworks as a desire for achieving a better taxonomy of ERP implementation methodologies. This paper is useful to researchers who are interested in ERP implementation methodologies and frameworks. Results will serve as an input for a classification of the existing ERP implementation methodologies and frameworks. Also, this paper aims also at the professional ERP community involved in the process of ERP implementation by promoting a better understanding of ERP implementation methodologies and frameworks, its variety and history

UK utility data integration: overcoming schematic heterogeneity

In this paper we discuss syntactic, semantic and schematic issues which inhibit the integration of utility data in the UK. We then focus on the techniques employed within the VISTA project to overcome schematic heterogeneity. A Global Schema based architecture is employed. Although automated approaches to Global Schema definition were attempted the heterogeneities of the sector were too great. A manual approach to Global Schema definition was employed. The techniques used to define and subsequently map source utility data models to this schema are discussed in detail. In order to ensure a coherent integrated model, sub and cross domain validation issues are then highlighted. Finally the proposed framework and data flow for schematic integration is introduced

Aligning a Service Provisioning Model of a Service-Oriented System with the ITIL v.3 Life Cycle

Bringing together the ICT and the business layer of a service-oriented system (SoS) remains a great challenge. Few papers tackle the management of SoS from the business and organizational point of view. One solution is to use the well-known ITIL v.3 framework. The latter enables to transform the organization into a service-oriented organizational which focuses on the value provided to the service customers. In this paper, we align the steps of the service provisioning model with the ITIL v.3 processes. The alignment proposed should help organizations and IT teams to integrate their ICT layer, represented by the SoS, and their business layer, represented by ITIL v.3. One main advantage of this combined use of ITIL and a SoS is the full service orientation of the company.Comment: This document is the technical work of a conference paper submitted to the International Conference on Exploring Service Science 1.5 (IESS 2015

Towards a Traceable Enterprise Architecture for Small- and Medium-Sized Enterprises

The practice of Enterprise Architecture (EA) continues to develop. Many large organizations are using EA processes and practices to help manage their complex set of integrated processes and applications. The set of integrated processes and applications required to meet their unique business requirements. Large organizations inherently recognize that an effective EA assists the enterprise to determine its desired direction. The resulting EA is then used to help manage the changes required to achieve the enterprises chosen destination. In a similar manner, Small- and Medium-Sized Enterprises (SMEs) can benefit from EA practices. Achieving these benefits requires EA practices and tools be appropriately scaled to the size of the enterprise. My objective is to address the EA needs of SMEs by researching appropriate EA best practices, building artifacts that embrace these practices, and then evaluating these artifacts to determine how well they meet the need

Semantic discovery and reuse of business process patterns

Patterns currently play an important role in modern information systems (IS) development and their use has mainly been restricted to the design and implementation phases of the development lifecycle. Given the increasing significance of business modelling in IS development, patterns have the potential of providing a viable solution for promoting reusability of recurrent generalized models in the very early stages of development. As a statement of research-in-progress this paper focuses on business process patterns and proposes an initial methodological framework for the discovery and reuse of business process patterns within the IS development lifecycle. The framework borrows ideas from the domain engineering literature and proposes the use of semantics to drive both the discovery of patterns as well as their reuse

Bibliometric Analysis of Citation Trends and Publications on E-government in Southern African Countries: A Human-computer Interactions and IT Alignment Debate

Due to technology adoption, many countries are embracing e-government. This study presents the growth and pattern of research on e-government articles and conference proceedings internationally, by scholars in the Southern African countries. It presents research patterns, trends and current gaps in e-government, as well as the most prolific authors and the level of outputs’ prominence. This paper uses bibliometric tools to present the analysis of articles on Web of Science, Scopus and Google Scholar databases. R computational programming for big data analysis was used to generate summarized metrics. The citation sample size was (n = 33,689), µ = 625, and the outputs impact based on total link strength of citations were; min =11.0, max = 1,686.0 and µ = 118.2, showing the Southern African scholars outputs visibility and prominence on e-government research. The findings present the most prolific authors in the Southern African region and the prominence of their outputs on e-governance. The study, through the computational synthesis of the data, also reveals some of the missing links in e-governance research designs and implementation. Furthermore, the study indicates that the service-oriented design of e-government platforms are still lacking, and the integration of Information Technology (IT) alignment, which is necessary to successfully implement e-government is lacking. The use and integration of mobile technology to enhance citizen-centric and participatory public governance platform and e-government implementation is not sufficiently addressed. Therefore, there is need to measure the maturity level of e-government IT deployment, its user-interfaces, as well as the design of an e-government that is able to respond to often embryonic and heterogeneous needs of citizens
